A kasuwa, mun fi saba da kayan yumbu na musamman: silicon carbide, alumina, zirconia, silicon nitride.Cikakken buƙatar kasuwa, bincika fa'idar waɗannan nau'ikan kayan da yawa.
Silicon carbide yana da abũbuwan amfãni daga in mun gwada da arha farashin, mai kyau yazawa juriya, high ƙarfi, babban hasara ne mai sauki oxidize, da wuya a sintering.Alumina shine mafi arha, kuma tsarin shirye-shiryen kayan albarkatun foda yana da girma sosai, yayin da zirconia da silicon nitrous oxide suna da fa'ida a bayyane game da wannan, wanda kuma shine ɗayan kwalabe na hana ci gaban na biyu.Silicon nitride, musamman, shine mafi tsada.
Dangane da aikin, kodayake ƙarfin, ƙarfi da sauran kayan aikin injiniya na silicon nitride da zirconia sun fi kyau fiye da alumina, yana da alama cewa aikin farashi ya dace, amma a zahiri akwai matsaloli da yawa.Na farko daga zirconia, yana da babban tauri, dalilin shine wanzuwar stabilizer, amma babban ƙarfinsa shine mai saurin lokaci, ba za a iya amfani da shi ba a babban zafin jiki da zafin jiki na lokaci mai mahimmanci yana hana haɓakar haɓakar iskar shaka ba daidai ba, ya kamata ya kasance. ya ce shi ne mafi ƙanƙanta a cikin ukun da ke kasuwa.Kuma silicon nitride, shima sanannen yumbu ne a cikin shekaru ashirin da suka gabata, ƙarfin girgiza zafin jiki mai jurewa da sauran ingantaccen aiki yana da kyau, amma amfani da zafin jiki yana ƙasa da sauran biyun;Tsarin shirye-shiryen silicon nitride shima ya fi alumina rikitarwa, kodayake aikace-aikacen siliki nitride lokaci ya fi zirconia kyau, amma kwatancen gabaɗaya har yanzu bai kai alumina ba.
Rashin tsada, aiki mai ƙarfi, rarrabuwar samfur na yumbu alumina ya zama farkon amfani, kuma an yi amfani da shi zuwa yumbu na musamman na yanzu.
